Steps to reproduce:

I created a handful of elements and made them red (#ff0000) in various ways, using:

  * background-color: #f00
  * background: linear-gradient(#f00, hsla(0, 100%, 50%, 1))
  * background: radial-gradient(#f00, hsl(0, 100%, 50%))
  * background: url(no-profile.png) // image with no colour profile
  * background: url(embedded-profile.jpg) // image with with colour profile
* Canvas
  * c.fillStyle = '#f00'; c.fillRect(0, 0, 200, 200);
  * fill: rgb(255, 0, 0)
* Image
  * <img src="no-profile.png"> // image with no colour profile
  * <img src="embedded-profile.jpg"> // image with with colour profile

I have set gfx.color_management.mode to 1 (full colour management) and have a properly calibrated wide gamut monitor.

Here is a test page that demonstrates this:

Actual results:

The boxes with with colour set by linear-gradient, radial-gradient and a canvas displayed with a very vivid red (i.e., without colour management). The rest were showing the correct red.

Here's a screenshot, with an embedded profile (the differences may not be visible on your screen):

Here's another screenshot, as sRGB with no embedded profile (the colours aren't right, but on my screen, imagine the orange squares are red, and the red ones are a very vivid red):

Expected results:

All of the boxes should appear to be the same colour.
